Abstract
A sheet feeding apparatus is provided having a first rotary member for feeding a sheet material and a second rotary member arranged at a downstream side of the first rotary member in the sheet feeding direction, for further feeding the sheet material. A drive source rotates the first and second rotary members. A transmitter is adapted to be engaged to rotate the first rotary member in the sheet feeding direction and to be disengaged to stop the second rotary member, when the drive source is rotated in one direction. The transmitter is adapted to be disengaged to stop the first rotary member and to be engaged to rotate the second rotary member in the sheet feeding direction, when the drive source is rotated in the other direction. The rotation of the first rotary member is prohibited in the sheet feeding direction at the start of rotation of the drive source in the other direction.
